I got myself a norns shield and after a week I realised I really wanted to use a grid with it. There are no varibright grids available anywhere but I found a used grid 64 40h. It looks as if the case was 3D printed but I assume it was proper. I have tried it out with some different norns scripts after altering the code slightly but I always run into the same problem. When the script calls
g.all(0) for the grid all the light flickers and is not properly redrawn. If I comment out
all(0) everything works except lights are obviously not turned off properly.
I tried looking through the norns recipes and I searched the forum but I can’t find an explanation of why I am seeing this behaviour. I also tried slowing down the redraws but oddly that does not make any difference, which I was a bit surprised of.
Hopefully I haven’t overlooked something obvious. Thanks for your help!
